  • Stabilization Of Oscillater, Synchronisation, Frequency Synthesizers (AREA)

Abstract

PURPOSE: To secure a stabilized modulation over a wide band by putting the output of 1st and 2nd voltage control oscillator which input a modulation signal into a phase detector and then by giving the detector output to 1st voltage control oscillator via a low band pass filter.
